Intermediate-mass fragments (IMF) from the reaction 209 Bi+ 136 Xe at E lab A =28 MeV have been measured in coincidence with other charged reaction products, as well as with neutrons. The IMF emission patterns are seen to exhibit signatures of two me

In-beam [gamma]-ray spectroscopic studies of [sup 182]Hg have revealed five new bands. The 2[sup +] state of the prolate band has been identified at an energy of 548.6 keV and is higher than in [sup 184]Hg. A two parameter band mixing calculation res

Highly fragmented exit channels produced by the decay of excited 24Mg projectiles were detected. The longitudinal velocity spectra of protons and alpha particles from such channels are offset. This offset is consistent with post-breakup Coulomb accel

A simple 4 π charged-particle sensitive detector useful for γ-ray spectroscopy is described. The detector is a plastic scintillator tube, which surrounds the target. The tube is segmented into four optically isolated cylindrical arcs. The tube is a

Exclusive measurements of neutrons and charged products have been performed using a combination of 4{pi} neutron and 4{pi} charged-particle detectors. The maximum observed energy dissipation corresponds to only approximately one-half of the available
